IMPROVEMENT IN COMBINED CAR-VENTILATORS AND W ATER-COOLERS.

Specification forming part of Letters Patent No. 1 63,5 13, da ed May18, 1875; application filed February 6, 1875.

To all whom it may concern Be it known that 1, ANDREW J. MORRISON, ofTroy, in the county of Rensselaer and State of New York, have inventedcertain new and useful Improvements in Railroad-Oar Ventilators andWater-Coolers; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to which it pertains to make and use the same, referencebeing had to the accompanyingdrawings and to the letters of referencemarked thereon, which form a part of this specification.

Figure 1 is a perspective view of my invention, with a portion of theouter wall or cylinder removed, and without the covers of the cylinders.Fig. 2 is a plan or top view of the parts shown in Fig. 1, theice-buffers being removed; Fig. 3, a part sectional elevation; Fig. 4, asectional side elevation; Fig. 5, a detached view of the spring stool orbuffer.

This invention relates to a means for ventilating railroad-cars; andconsists in combining, with a tank or reservoir for drinking-water andsuitable ice-chambers, a series of air chambers, compartments, orpassages, arranged in such a manner in relation thereto as to cause theair to be brought in contact with the walls of the ice-chambers andwatertank, and be cooled previous to entering the car, and also freedfrom any impurities by coming in contact with the Waste-water in a panor drawer placed beneath the ice-chambers to receive the drippings fromthe ice, as will be hereinafter more fully described.

In the drawings, A represents the outer wall or cylinder of theapparatus, the same being placed in one corner of the car; and B, theinner cylinder, having a central reservoir or tank, 0, fordrinking-water, and provided with a suitable faucet, a, for drawing offthe water when required. Surrounding the tank 0 are icechambers b, inthe bottom of which are small perforations or leak-openings, to allowthe water from the ice to pass down into a removable drip-pan or drawer,D. At the bottom of these chambers are placed spring stools or buffersH, consisting of a flat plate, 0, provided with suitable springs i uponits under side, the purpose of which is to deaden the Shock upon thedropping in of the ice, and

thereby prevent any injury to the bottom or sides of the ice-chambers.The two compartments or air-passages d d (the sides of which form thewalls of the ice-chambers) are closed at the top, and communicate withbranch tubes 0 0, connected to a main pipe, E, leading out through theroof or top of the car, and to which is attached a suitable cowl, F.Diagonally opposite the compartments or air-passages cl d are similarair-passa,g ;es f f, open at bottom, and through which the air passesupward after leaving the compartments or airpassages d d, and afterbeing relieved from all impurities by'coming in contact with thewastewater in the drip-pan or drawer D. These airpass'ages ff haveopeningsj near the top, by means of which communication is made betweensaid passages and the annular space 9, formed by the inner cylinder Band the outer wall or cylinder A of the apparatus. Within the annularspace 9 are inclined partitions hh, as illustrated in Fig. 1, causingthe air to pass, previous to its being distributed into the car, aroundthe outer side of the inner cylinder B, and thereby coming again incontact with the walls of the ice-chambers. An outlet-pipe, G, isconnected to the outer cylinder A near its base, communicating with theannular space g, the air passing from the same into the outlet-pipe,after which it may be distributed in any suitable manner throughout thecar. A cover, H, as seen in Fig. 4, Sheet 2, of the drawings, is placedover the inner cylinder B, confining the air within the compartments orair-spaces, and also keeping the drinking-water clean and pure. An outercover, I, closes the entire top of the apparatus, and prevents the air,as it passes into the annular space g, from escaping.

The operation of my ventilator is as follows: As the car is in motionthe mouth of the cowl faces the wind, the air passes down through themain pipe E into the branch tubes 0 e, and thence into the compartmentsor air-passages d d, coming in contact with the sides or walls of theicechambers b 12, passing out into the bottom of the apparatus, where itis brought in contact with the waste-water in the drippan or removabledrawer D, and the natural jarring motion of the cars, keeping the waterin a continual state of agitation, filters and relieves the air from anyimpurities or particles of dust and cinders, after which it is againbrought in contact with the sides of the ice-chambers by taking a courseup through the compartments or air-passages f f, from whence it passesout through suitable openingsj therein into the annular space 9, and, bymeans of the two inclined partitions h h, is carried down and around theouter side of the inner tank B, coming a third time in contact with thesides of the ice-chambers, and is thereby thoroughly cooled beforeentering the car, after which it may be distributed at different pointsin the car by means of suitable pipes and registers.

It will be seen that the ice in the ice-chambers serves the doublepurpose of keeping the drinking-water in the tank cool, and at the sametime cooling the air before it passes out into the car, and also thewaste-water in the drip-pan or drawer serving to purify the air by beingbrought in contact therewith.

WVith this apparatus the ordin ary ventilators at the top of the carmust always be sufficiently opened to allow the foul gases or vitiatedair to escape, while a fresh supply of pure air is constantly introducedfrom below; and, to secure the best results, the windows and doorsshould be closed whenever the car is in motion.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. A combined water-cooler and ventilator, substantially as described,wherein the air to be cooled is caused to pass through suitable passagesin contact with ice-chambers, as

specified, and afterward filtered from all impurities by coming incontact with water in a drip-pan arranged below a centrally-locatedwater-tank to receive the drippings therefrom, as set forth.

2. The inner cylinder B, provided with airpassages d d andff,ice-chambers b, and central water-tank O, in combination with the outercylinder A, substantially as and for the purpose specified.

3. In combination with the inner cylinder B, constructed substantiallyas described, the outer cylinder A, annular space 1, and inclinedpartition h, for the purpose set forth. 7

at. In combination with the inner cylinder B, constructed, as described,with suitable airpassages and ice-chambers, the drip-pan or drawer D,for the purpose set forth.

5. The combination, with the outer cylinder A and annular space 9,having inclined partitions h h, of the inner cylinder B, provided withair-passages d d and ff and ice-chamber b, as and for the purpose setforth.

6. The water-cooler and ventilator herein described, consisting of theouter cylinder A, with cover I, inner cylinder B, provided with centralwater tank or reservoir O, ice-chamhers I), air-passages ff and d d, andcover H, tubes 0 6, main pipe E, and drip-pan or drawer D, substantiallyas described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

A. J. MORRISON.
